Rockies starter Jorge De La Rosa was removed early from his start during the first game of Tuesday's doubleheader against Arizona in the middle of an at-bat in the third inning. The Denver Post reports that De La Rosa was diagnosed with a complete tear of the ulnar collateral ligament in his left (throwing) elbow. Tommy John surgery is almost a definite and De La Rosa and his agent will talk Wednesday to discuss when he'll undergo the surgery. De La Rosa, who is almost definitely out for the rest of the season, left the game after going 2 1/3 innings, leaving runners on second and third base. His record stands at 5-2 with a 3.51 ERA. “Wow. I just feel so badly for him and the organization. There was nothing anybody could do about it. It’s just one of those things that happens,” De La Rosa's agent Paul Cohen said.
